Technical Field

[0001] This application relates to the field of welding head heating technology, specifically a welding head heating fixture. Background Technology

[0002] Heating the welding head plays a crucial role in the welding process. Its main purpose is to increase the plasticity of the material, help reduce cracks and defects generated during welding, and ensure that uniform heating results in a more homogeneous microstructure and properties of the weld joint, improving the joint's strength and toughness, reducing welding stress concentration, and lowering the risk of joint failure.

[0003] The welding head heating method uses a heating rod to heat the welding head locking base. During the heating process, the temperature of the heating base can be detected by a thermocouple, allowing personnel to observe precise temperature changes in real time. Furthermore, the exterior is protected by heat insulation material to prevent excessively high external temperatures.

[0004] When the welding head is used for heating and welding, the high temperature of the welding head comes into contact with the workpiece to be welded. At this time, the high temperature of the welding head will melt the contact area of ​​the workpiece. The melting of the workpiece will cause harmful gases inside to be released into the air.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0026] Example 1

[0027] Please see Figures 1-4 This embodiment provides a technical solution: a welding head heating fixture, including: a welding head fixing base 1, a heating rod 2, a detection thermocouple 3, an absorption and purification component 4, and a linkage cleaning component 5;

[0028] The main body of the welding head heating fixture consists of a welding head fixing base 1, a heating rod 2 set on the top of the outer wall of the welding head fixing base 1, and a detection coupler 3 set next to the heating rod 2 on the outer wall of the welding head fixing base 1. When the heating rod 2 is connected to the power supply, the current will flow through the heating element. Since the heating element has a certain resistance, the current will generate heat when it passes through. The detection coupler 3 measures the temperature by utilizing the thermoelectric effect when two conductors or semiconductors A and B of different materials form a closed circuit and the temperatures T and T0 of the two junctions are different. The above is the prior art and will not be described in detail below.

[0029] Absorption and purification component 4 is disposed on one side of the outer wall of the welding head fixing base 1. The absorption and purification component 4 includes a first pipe 401 fixed to one side of the outer wall of the welding head fixing base 1, a second pipe 402 fixed to the outer wall of the welding head fixing base 1 next to the first pipe 401, and a water storage tank 403 extending through and fixed to one end of the first pipe 401 and the second pipe 402. The water storage tank 403 has an inlet, and round holes are provided at the top and bottom of the water storage tank 403. The second pipe 402 is fixed to the other side of the second pipe 402. The electric fan 404 inside the end is composed of fan blades connected by a shaft driven by a motor. A water pump 405 is installed on the outer wall of the water storage tank 403. A filter screen 406 is welded into the bottom round hole of the water storage tank 403 and a nozzle 407 is installed into the top round hole of the water storage tank 403. The inlet and outlet of the water pump 405 are connected to the nozzle 407 at the bottom round hole of the water storage tank 403 through pipes. The linkage cleaning component 5 is installed inside the water storage tank 403.

[0030] The welding head fixing base 1 can clamp and fix the welding head. Then, the heating rod 2 is activated. When the heating rod 2 is working, it can heat the welding head fixing base 1 and the welding head inside by electric heating. During the heating process, the temperature can be detected in real time by the detection thermocouple 3. When the welding head comes into contact with the workpiece after heating and generates harmful gases, the absorption and purification component 4 is used to absorb and purify the harmful gases. The linkage cleaning component 5 can effectively prevent the absorption and purification component 4 from becoming blocked during operation.

[0031] Water is injected into the water storage tank 403, and the water pump 405 is started. At this time, the water pump 405 draws water filtered by the filter screen 406 from the bottom of the water storage tank 403 and delivers it to the inside of the nozzle 407, thereby creating a water curtain inside the water storage tank 403. The electric fan 404 is started. When the electric fan 404 is working, it can absorb the harmful gases generated by connecting to the water storage tank 403 through the first pipe 401 and the second pipe 402. After the harmful gases come into contact with the water curtain of the water storage tank 403, the harmful gases dissolve into the inside of the water curtain. The impurities can be retained inside the water storage tank 403 by the filter screen 406, so that the impurities will not participate in the water circulation of the water pump 405 and cause the nozzle 407 to be blocked.

[0032] Example 2

[0033] Please see Figures 1-4 This embodiment provides a technical solution: a welding head heating fixture, including: rod 501, rod 502, rod 503, cleaning brush 504, bevel gear 505, bevel gear 506, bevel gear 507, and bevel gear 508;

[0034] The linkage cleaning assembly 5 includes a first rod 501 vertically welded to the shaft of the electric fan 404 at one end, a second rod 502 horizontally positioned at the bottom of the first rod 501 at one end, and a third rod 503 vertically positioned at the bottom of the other end of the second rod 502. The second rod 502 is fixed inside the second pipe 402 by rotating it into the bearing of the positioning block. The third rod 503 is fixed inside the water storage tank 403 by rotating it into the bearing of the positioning block. A cleaning brush 504 is fixed at the bottom of the third rod 503, and the brush surface of the cleaning brush 504 is attached to the upper surface of the filter screen 406.

[0035] The first bevel gear 505, which is fixed at the bottom of the first rod 501, engages with the second bevel gear 506 and the third bevel gear 507, which are fixed at both ends of the second rod 502, and engages with the fourth bevel gear 508, which is fixed at the top of the third rod 503. The first bevel gear 505 meshes with the second bevel gear 506, and the third bevel gear 507 meshes with the fourth bevel gear 508.

[0036] During the rotation of the electric fan 404, it can synchronously drive the first rod 501 and the first bevel gear 505 to rotate. The first bevel gear 505 meshes with the second bevel gear 506 at one end of the second rod 502, thereby driving the third bevel gear 507 at the other end of the second rod 502 to rotate synchronously. At this time, the third rod 503 meshes with the third bevel gear 507 through the fourth bevel gear 508, so that the cleaning brush 504 on the third rod 503 can adhere to the surface of the filter screen 406 to clean the attached impurities and prevent the filter screen 406 from becoming clogged.

[0037] The implementation principle of the welding head heating fixture of this application is as follows:

[0038] First, the welding head fixing base 1 can clamp and fix the welding head. Then, the heating rod 2 is activated. When the heating rod 2 is working, it can heat the welding head fixing base 1 and the welding head inside by electric heating. During the heating process, the temperature can be detected in real time by the detection thermocouple 3. When the welding head comes into contact with the workpiece after heating and generates harmful gases, the absorption and purification component 4 is used to absorb and purify the harmful gases. The linkage cleaning component 5 can effectively prevent the absorption and purification component 4 from becoming blocked during operation.

[0039] Next, water is injected into the water storage tank 403, and the water pump 405 is started. At this time, the water pump 405 draws water filtered by the filter screen 406 from the bottom of the water storage tank 403 and delivers it to the inside of the nozzle 407, thereby creating a water curtain inside the water storage tank 403. The electric fan 404 is then started. When the electric fan 404 is working, it can absorb the harmful gases generated by connecting to the water storage tank 403 through the first pipe 401 and the second pipe 402. After the harmful gases come into contact with the water curtain of the water storage tank 403, the harmful gases dissolve into the inside of the water curtain. The impurities can also be retained inside the water storage tank 403 by the filter screen 406, so that the impurities will not participate in the water circulation of the water pump 405 and cause the nozzle 407 to become clogged.

[0040] Finally, during the rotation of the electric fan 404, it can synchronously drive the first rod 501 and the first bevel gear 505 to rotate. The first bevel gear 505 meshes with the second bevel gear 506 at one end of the second rod 502, thereby driving the third bevel gear 507 at the other end of the second rod 502 to rotate synchronously. At this time, the third rod 503 meshes with the third bevel gear 507 through the fourth bevel gear 508, so that the cleaning brush 504 on the third rod 503 can adhere to the surface of the filter screen 406 to clean the attached impurities and prevent the filter screen 406 from becoming clogged.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application.
